How to open a link from one UIWebView to another UIWebView? - ios

Question

I'm building an iOS app.
I have HTML content in a UIWebView with hyperlinks, and I'm unable to open a link to another UIWebView.
I used UIWebView as a subview of ViewController. Here is the code:
- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType
{
switch (navigationType) {
case UIWebViewNavigationTypeLinkClicked: { //this is when a user tap is detected
//write the handling code here.
isWebViewLoaded = false; //set this to false only if you open another view controller.
return NO; //prevent tapped URL from loading inside the UIWebView.
}
// some other typical parameters within a UIWebView. Use what is needed
case UIWebViewNavigationTypeFormResubmitted: return YES;
case UIWebViewNavigationTypeReload: return YES;
//for all other cases, including UIWebViewNavigationTypeOther called when UIWebView is loading for the first time
default: {
if (!isWebViewLoaded) {
isWebViewLoaded = true;
return YES;
}
else
return NO;
}
}
}

You only need to segue to a new controller with a web view, and pass the request to it. So something like this in your first case,
case UIWebViewNavigationTypeLinkClicked: { //this is when a user tap is detected
[self performSegueWithIdentifier:#"Next" sender:request];
isWebViewLoaded = false; //set this to false only if you open another view controller.
return NO; //prevent tapped URL from loading inside the UIWebView.
}
Notice that the sender argument in performSegueWithIdentifier:sender: is the request returned by the delegate method. Pass this request to a property in the view controller you're segueing to,
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(NSURLRequest *)sender {
NextViewController *next = segue.destinationViewController;
next.request = sender;
}
Finally, use that request to load the web view in NextViewController.
